Episode Overview

This episode of The New Yorker Radio Hour, hosted by David Remnick, explores two intense and timely topics:

• The ethical, scientific, and personal dilemmas around "human challenge trials" for COVID-19 vaccine development, featuring in-depth discussion with New Yorker writer Larissa MacFarquhar, a young volunteer, and leading scientists.
• An analysis of the legal and social dynamics surrounding the killing of Ahmaud Arbery in Georgia, with Jelani Cobb interviewing law professor Ira P. Robbins on the complicated intersection of citizen's arrest laws, self-defense, race, and justice.

Segment 1: The Morality and Science of Human Challenge Trials (00:13–16:42)

Key Discussion Points

The Volunteer’s Story and Family Concerns

• AB Rohrek, a 20-year-old undergraduate, aspires to participate in human challenge trials—clinical trials where volunteers are deliberately exposed to COVID-19 post-vaccination to expedite vaccine development (00:13).
• AB’s mother, Elaine Rohrek, expresses deep concern, especially as AB has only one kidney (00:57–01:58).
  • Elaine Rohrek (02:18): “You're doing this for the universe, but you are my universe, so it's a little bit hard to...”

What Are Human Challenge Trials?

• Larissa MacFarquhar explains:
  • Standard vaccine trials take months or longer because participants are simply observed in the community to see who contracts the disease (03:00).
  • In human challenge trials, volunteers are vaccinated and then intentionally exposed to the virus, producing results in weeks, potentially saving thousands of lives (03:00–04:01).

Scope of Interest and Organizing Group

• Tens of thousands worldwide have signed up, according to AB and MacFarquhar. The initiative is led by “One Day Sooner,” aiming to trim the vaccine timeline by even a single day to save lives (05:05).

The Case for Challenge Trials

• Mark Lipsitch, epidemiologist and co-author of a foundational paper advocating the trials, supports the ethical rationale (06:02).
  • Mark Lipsitch (06:10): "We really face a challenge that's very much worse than challenges we've faced before from infectious diseases... even a very small benefit... could be enormously valuable to humanity."
  • Draws parallels with other professions where individuals take calculated risks for societal benefit (06:02–07:27).

The Emotional Dilemma for Families

• MacFarquhar and Remnick probe the ethics if one’s own child wanted to participate.
  • Mark Lipsitch (08:26): "I would probably try to discourage them, to be honest…this is a decision that should be done really with a lot of reflection and with understanding that there's a risk that something bad will happen."

Risks and Scientific Uncertainties

• Not all young people experience mild cases of COVID-19, and many effects are still unknown (09:13–09:55).
• Angela Rasmussen, virologist, opposes challenge trials, citing both ethical and scientific limitations:
  • Difficulty of true informed consent when risks are unknown (10:30).
  • Volunteers’ risk profiles don’t match those most in need of a vaccine (older/health-compromised people), reducing trial relevance (12:05–12:47).
  • Angela Rasmussen (10:30): "We know so little about this virus other than that it can be lethal, that it's very difficult for a subject in one of these trials to give informed consent."

Alternative Paths to Help

• Rasmussen urges prospective volunteers to enroll in standard phase 3 trials instead, making a crucial contribution without unnecessary risk (14:34).

Altruism and Motivation

• Remnick wonders if youth and idealism fuel such volunteerism; MacFarquhar argues that risk-taking for moral reasons transcends age, although having dependents may curb altruistic risk-taking (15:33–16:42).
  • Larissa MacFarquhar (15:33): “When I was researching my book, I talked with people of all ages who were just as willing to risk themselves for their principles as AB is…they didn’t want to just be comfortable.”

Notable Quotes & Moments

• AB Rohrek (01:58): "I think I feel a sort of broader sense of obligation, or almost like a principled obligation... I guess, you know, why shouldn't it be me?"
• Elaine Rohrek (02:18): “You're doing this for the universe, but you are my universe...”
• Mark Lipsitch (06:10): “If we really thought it was not acceptable for people to voluntarily take on risk on behalf of others, then we would have to shut down our police, fire, EMT and military operations...”
• Angela Rasmussen (10:30): “We know so little about this virus...it’s very difficult for a subject in one of these trials to give informed consent.”

Segment 2: The Killing of Ahmaud Arbery and the Law (18:12–27:46)

Key Discussion Points

Legal Backdrop and Citizen’s Arrest

• Jelani Cobb and law professor Ira P. Robbins unpack the logic behind why local Georgia prosecutors initially viewed the McMichaels’ pursuit of Ahmaud Arbery as a lawful citizen’s arrest (18:12).
• Citizen’s arrest law in Georgia hinges on specifics (felony vs. misdemeanor) and is meant to empower citizens to detain, not to police or use deadly force (18:42–20:11).

Self-Defense and Stand Your Ground

• Robbins distinguishes between citizen’s arrest and self-defense laws, including “stand your ground,” which removes duty to retreat, making confrontations more volatile (20:08–21:27).

Race, Law, and Pretext

• Discussion points toward a “deadly combination” of ambiguous laws and racial profiling (22:16).
  • Ira P. Robbins (22:16): "What we're seeing here is a deadly combination of the law of citizens arrest, flawed self-defense laws...and arguably racial profiling as well."
  • Suggests actions taken by the McMichaels may have been pretextual, with citizen’s arrest law used to justify what began as racially motivated suspicion.

The Everyday Perspective: Minor Offenses, Major Consequences

• Cobb’s personal reflection: common behaviors (like curiosity about a construction site) are not criminal, yet in Arbery’s case resulted in lethal force (24:03).
  • Jelani Cobb (24:03): "The idea that that could be provocation for an armed pursuit was unnerving and shocking to me."

The Need for Change

• Robbins criticizes the persistence of outdated citizen’s arrest laws, arguing that their misuse is dangerous and can act as a pretext for vigilantism and racially biased violence (25:59–27:46).
  • Ira P. Robbins (26:18): "A lot of laws whose time has passed stay on the books only because the legislature has not gotten around to repealing them...We don't want citizens arrest to become a pretext for an unfortunate end to situations that start with racial profiling."

Memorable Moments & Notable Quotes (with Timestamps)

• AB Rohrek (01:58): "I just feel this urge to be one of those people or framed the other way, I guess, you know, why shouldn't it be me?"
• Elaine Rohrek (02:18): "You're doing this for the universe, but you are my universe, so it's a little bit hard to—"
• Mark Lipsitch (06:10): “Even a very small benefit in terms of speeding up...could be enormously valuable to humanity.”
• Mark Lipsitch (08:26): “I would probably try to discourage them, to be honest.”
• Angela Rasmussen (10:30): "It's very difficult for a subject in one of these trials to give informed consent."
• Larissa MacFarquhar (15:33): “I definitely don't think it's just youth talking...When I was researching my book, I talked with people of all ages who were just as willing to risk themselves for their principles...”
• Ira P. Robbins (22:16): “A deadly combination of the law of citizens arrest, flawed self-defense laws...and arguably racial profiling as well.”
• Jelani Cobb (24:03): "The idea that that could be provocation for an armed pursuit was unnerving and shocking to me."
• Ira P. Robbins (26:18): "A lot of laws whose time has passed stay on the books...We don't want citizens arrest to become a pretext for an unfortunate end to situations that start with racial profiling."
